WINDOW.

SPECIFICATION forming part of Letters Patent No. 339,4:l-T dated April 6, 1886.

Application filed December 21, 1885. Serial No. 196,254.

To all "whom it may concern.-

Be it known that I, RICHARD Mason, of Hemsworth, near Pontefract, in the county of York, England, joiner and builder, and a sub jeot of the Queen of Great Britain, have invented certain new and useful Improvements in Windows, (for which I have received Letters Patent in England, No. 10,221, dated July 16, 1881;) and 1 do hereby declare that the following is sufficient. description of the invention to enable those skilled in the art to which it appertaius to carry the same into practical effect.

This invention relates to windows having a pivoted sash or sashes.

It consists, chiefly, in the combination, with a pivoted sash, of pivoted spring pressed strips which bear against the side edges of said sash, substantially as hereinafter set forth and claimed.

Said invention further consists of a lower sash hinged at its lower edge, in order that it may be conveniently cleaned from the inside of the room, in combination with a pivoted upper sash and a fastening for their meetingrails, substantially as hereinafter set forth and claimed.

Figure 1 is an elevation of a window and frame and adjustment in its complete state entirely closed up and fastened. Fig. 2 is a vertical sectional side elevation of the window and frame on line 1 2, looking toward the adjustable fastener. Fig. 3 is a front elevation of the same window and frame and fastening, with the top and bottom sashes bot-h opened out a certain distance. Fig. .i is a vertical sectional side elevation of Fig. 3 on line 34, looking toward the fastening A. Fig. 5 is a detail horizontal section of one side of the windowframe on the line 5 6 of Fig. Fig. 6 is a cross-sectional part plan of the frame, and top sash, B, closed up, as seen at 7 8, Fig. 1. Fig. '7 is a cross-sectional and part plan of the frame and bottom sash, C, as seen at 9 10, Fig. 1. Fig. 8 is a crossscction at 11 12, Fig. 9, showing the corner-bracket case D containing the spring E, which is mounted on the pivot of the metallic flaps or wings Fand F,for the purpose of giving them a constant distinct tendency to take the fiat position shown in Figs. 1, 6, and 9.

bottom portions of the top sash. B, so as to show more clearly the attachment of the flaps F to the hracket-case D at the top and the staple or socket It against the frame near the bottom of sash B. Fig. 10 is a part fullsized crosssection of the bottom bar, I), of the top sash, B, and the top bar, 0, of the bottom sash, C, which also shows how the fastening A operates in the socket or barrel A in opening the top sash, B, a short distance, for the purpose of ventilation, as shown. It will be seen that the thumbscrew A turns in the front plate, a, without moving outward or inward, and that the socket A is pivoted upon the axis a at or near the back end, which allows the screw to work smoothly when the top sash, B, is inclined from its natural vertical position.

On reference to the drawings it-will be seen that the lower sash, O, is hinged at 0, so that when the bolts, buttons, or other fastenings, m and m, are withdrawn, and the fastening A entirely withdrawn also, as shown at Fig. 4, the sash will hinge back as far as desired, so that the outside may be easily cleaned from the inside.

A simple kind of hinge may be used, when desired, of such a nature as to allow the sash to be lifted entirely away without unscrewing the hinges-such, for instance, as flat metal hooks or claws around a metal bar, or a hinge with a thumb-screw or other pin as a pivot; or it may be hung with pivots near the bottom of the stiles. This sash C closes up against a weather-proof or other head, P, as shown at Fig. 7. The upper sash, B, is pivoted'in the frame by the pivot It to side frame, L, and by the pivot n to the other side, L, of the frame.

In the case of doors or windows pivoted it is nearly impossible to keep them at all weather-tight, and they are often very loose and dangerous when partly open, especially when manipulated by inexperienced or weak persons, which is aggravated in windy weather. To obviate all this, I pivot metallic or other suitable strips, F and F, against each side of the frame in proximity to the upper or other pivoted sash, in such manner that the flat side of each strip will bear against said sash when the latter is closed, as shown in Fig. 6. The outer edge of each strip is rounded atf, and bears against said sash when the latter is .E by a suitable projection or catch.

partly open, as shown in Fig. 5, said strips turning on their pivots at D and it. These strips not only keep the sash weather-tight, but they prevent any shaking, because the coiled spring E constantly forces the strips F and F against the sash in the direction as shown by the arrow at Fig. 6, and they also prevent the sash from swinging about in a loose manner at any time or when in any position. These strips F, I prefer to make of moderately-soft tough rolled steel, or they may be made hollow and of brass or any desired kind of metal, or of any suitable material, and the edges may be covered with a soft surface material, if necessary. The top pivot is attached to the inner end of the coiled spring The top sash may be opened or shut with gutta-percha or other cords, with brass or other ends fastened to the upper part ofthe sash, and through a spring or other fastening on the bottom sashuniting bar; but I do not confine myself to any particular mode of operating the top sash when liberated from the hold of the fastening A. It will be noticed that the outside Window-frame is exceedingly simple and uncomplicated to make, and the timber required is minimized in quantity.

It will of course be clearly understood that my invention is applicable not only to windows, but to any analogous purposes, and that the strips F may be applied to other similar parts of windows and positions requiring similar treatment.

Having now described my invention, what I claim is The combination of pivoted spring-actuated strips F F with a pivoted sash, said strips bearing against the side edges of said sash, substantially as set forth.

In testimony that I claim the foregoing as my own I afiix my name in the presence of two witnesses.

RICHARD MASON.
